GENERAL DESCRIPTION

Each U.2 Industrial SSD integrates an NVMe PCIe SSD controller with NAND flash multi-chip packages, DRAM,
on-chip adaptive RAID, PCIe 4-lane signal port and hardware-based power loss protection circuitry in a standard
2.5-inch form factor housing.

group. This RAID group will be seamlessly
reconfigured to ensure continuous data loss protection,
without affecting the user capacity.

U.2 Industrial SSD

The heart of U.2 Industrial SSD is the SSD controller,
which translates standard PCIe signals into flash
media data and control signals. The following
components contribute to the drive’s operation.
1.1.1

1.1.6

Power Interrupt Data Protection is a mechanism tohelp prevent data corruption during unexpected power
failure events. Enhanced data integrity is supported by
the on-board power loss protection (PLP) circuitry withpower hold-up capacitors and the SSD controller’s
advanced firmware. The controller also proactivelyoptimizes the amount and stay time of the “in-flight”
data residing in the cache.

Industrial SSD Controller

The U.2 Industrial SSD’s controller is an advanced
ASIC which has been built for high-capacity drives
with sustained high performance and consistent, lowlatency operations.
1.1.2

Power Interrupt Data Protection

Internal Direct Memory Access (DMA)

U.2 Industrial SSD uses internal DMA allowing instantdata transfer from/to buffer to/from flash media.

1.1.7

1.1.3

U.2 Industrial SSD uses advanced ECC technology todetect and correct errors, ensuring data integrity andextending the SSD lifespan.

Power Management Unit (PMU)

The PMU controls the power consumption and power
on/off work flow of U.2 Industrial SSD. The Flash File
System handles inadvertent power interrupts and has
auto-recovery capability to ensure U.2 Industrial
SSD’s user data integrity. For regular power
management, the host should set the Shutdown
Notification (CC.SHN) field to 01b to indicate a normal
shutdown operation and wait for the drive to indicatethat shutdown processing has been completed by
updating the Shutdown Status (CSTS.SHST) field to10b before powering down the drive.
1.1.4

1.1.8

1.2

1. Manages and optimizes the data access of flash
media
2. Provides flash media wear leveling to spreadthe flash writes across all memory address
space to increase the longevity of flash media
3. Keeps track of data file structures

1.3

Advanced Data Security

Advanced data security measures include end-to-end
data path protection and secure erase support (Format
NVM command). The User Data Erase is an effective
method to quickly wipe all user content. The
Cryptographic Erase (crypto erase) is used to reset theencryption key with which the user data in the NVM
subsystem was previously encrypted. U.2 Industrial
SSD supports industry standard AES-256 encryption
to protect sensitive user data.

On-Chip Adaptive RAID

By default, U.2 Industrial SSD uses 15+1 RAID. Whenan uncorrectable read error occurs in one NAND die,the SSD will quickly reconstruct the affected data fromthe data on the other 15 NAND die in the same RAIDGLS FS0019 Rev. 01

Intelligent NAND Management

U.2 Industrial SSD’s NVMe PCIe controller uses
advanced wear-leveling algorithms to substantiallyincrease the longevity of NAND flash media. Wearcaused by data writes is evenly distributed in all or
select blocks in the device that prevents “hot spots” inlocations that are programmed and erased extensively.
This effective wear-leveling technique results in
optimized device endurance, superior data retention
and higher reliability required by long-life applications.

Multi-tasking Interface

The multi-tasking interface enables concurrent Read,
Program and Erase operations to multiple NAND flashmedia.

The embedded flash file system is an integral part ofU.2 Industrial SSD. It is integrated in the controller’s
firmware that performs the following tasks:
